How much does gutter installation cost in 2026?

Gutter installation costs $600 to $2,200 for a typical home, with a national average around $1,180. On a per-foot basis, expect $3 to $50 per linear foot depending heavily on material — vinyl and aluminum sit at the affordable end, while zinc and copper are premium options. Use our free calculator above for an instant estimate based on your home's linear footage, material and number of stories.

Gutter installation cost calculator — by material

K-style vs. half-round gutters

K-style gutters — flat-backed with a decorative front profile resembling crown molding — are the standard choice for most homes. They hold more water per linear foot than half-round gutters and are generally easier and cheaper to install. Half-round gutters have a rounded, historic aesthetic often chosen for older or higher-end homes, but typically add $1 to $2 per linear foot due to more specialized installation requirements.

Seamless vs. sectional gutters

This is the biggest installation-method decision, and it affects both cost and long-term performance.

Nearly all professional gutter installers use seamless systems today because the leak-reduction benefit is well established — on a typical 150-foot job, the seamless premium is often only $150–$400 total, which is why our calculator uses seamless as the default assumption for its per-foot rates.

How many linear feet of gutter do I need?

Linear footage roughly follows your home's footprint perimeter, not its total square footage (a 2-story home has less roofline per square foot than a 1-story home of the same size). As a rough starting point:

These are estimates — an irregular roofline with multiple gables or dormers can need more footage than a simple rectangular footprint of the same square footage.

Does homeowners insurance cover gutter replacement?

Generally, only if the damage results from a sudden, covered peril — a storm, falling tree branch, or similar event. Normal wear and tear, age-related deterioration, or gutters that simply weren't maintained aren't covered under a standard policy. If a storm damaged your gutters, document it with photos immediately and contact your insurer before starting repairs.

Five inch or six inch is not a cosmetic choice

Most quotes default to 5-inch because it is what most homes have. Whether that is right for your roof is a capacity question, and getting it wrong is the most expensive mistake available on a gutter job.

A 5-inch gutter holds roughly 1.2 gallons of water per foot. A 6-inch holds around 2.0 — close to 67 percent more — and pairs with larger 3×4 inch downspouts rather than 2×3 inch.

Two things push you toward 6-inch regardless of what is already up there: a large or steep roof plane concentrating water into one run, and a climate with intense short downpours rather than steady drizzle. Roof area feeding the run matters more than the length of the run itself.

Downspouts do half the work

A gutter that cannot drain is just a trough. The general guidance is one downspout for roughly every 40 feet of run, plus additional outlets wherever the gutter changes direction at a corner.

Undersized or too-few downspouts produce the same symptoms as an undersized gutter — water sheeting over the front edge in heavy rain — which is why replacing gutters without adding outlets sometimes fails to fix the original complaint.

Where the water goes after the downspout matters just as much. Discharging at the base of the wall puts it straight back against the foundation, which is the problem gutters exist to prevent.

Pitch and hanger spacing: the install details that decide lifespan

• Pitch. Generally around 1/16 to 1/8 inch of fall per foot toward the outlet. Too little and water stands in the trough; too much and it is visible from the ground.
• Hanger spacing. Commonly every 24 to 36 inches for aluminum K-style. Tighten toward 24 inches for 6-inch gutters, and in any climate where ice or wet debris loads the trough.
• Fascia condition. Hangers are only as good as the timber they screw into. Rotten fascia has to be replaced first, and a quote that ignores visibly soft fascia is a quote that will fail.

What undersized gutters actually cost

The saving from choosing 5-inch on a house that needed 6-inch is typically erased by the first fascia repair, which commonly runs into four figures. Before that bill arrives you will usually see the warning signs: water spilling over the front edge during heavy rain, staining down the siding, washed-out planting beneath the run, and splashback eroding soil at the foundation.

That last one is the expensive path. Water repeatedly delivered to the base of the wall is how gutter problems turn into basement problems — our basement waterproofing calculator prices that side of it, and the gutter guards guide covers whether protection is worth adding while the crew is already there.
